WHERE aufnr = p_aufnr
%_HINTS MSSQLNT 'TABLE &TABLE& ABINDEX(ZSN), FASTFIRSTROW'.
additional information in oss notes: 133381, 129385, 159171
Problems with indexes, try the following:
Force an "update statistics" (this should happend automatically in MSSQL 7 and up).
Update Stats on one table:
USE DEV
UPDATE STATISTICS bsas
Update Stats on all tables:
USE DEV
EXEC sp_updatestats
Refreshing the statistics force the Stored Procedures to be recompiled again and the execution plans to be updated. The following command should have similar effect:

For all entries
When using for all entries in a select statement with an empty internal table, not only does it get all entries for the selected where clause for the desired field in the for all entries table, it IGNORES the rest of the WHERE clause, meaning it will retrieve every single entry in the SELECT FROM table. Usually, this is not encountered because you should always check for an empty table prior to doing a FOR ALL ENTRIES select, but if you wanted to use the other conditions in the where clause you will not be able to. Pretty stupid on SAP's part.

Methods Being Displayed through .Net Connector
I marked several BAPI methods as Modeled and Implemented throughtransaction SWO1. This removes the method from the BAPI Explorer, butthey are still being displayed through .Net Connector. Is there anywayto hide Methods from the .Net Connector until they are Released?
There might be small differences in the view of BAPI explorer in SAPGUI and Visual Studio. If you need another view, you cantry to select the "Hierarchical" node and change the "X"sesin the property window before you expand the node.Which methods appear inside of a BOR class is mainly controlledif there is an implementation specified(property Abapname is not empty). If you see more methods thanyou want to have in your proxy, the easiest is either droping theBOR object and deleting the methods you don't like from the designer,or drag the methods you need individually. Note that draggingindividual method would not do some auto-customizing (e.g.use of Key-fields and so on).

Generate Fast Entry Screen Templates
RFFAKP01
Short text
Generate Fast Entry Screen Templates
Description
Generate Fast Entry Screen Templates
Description
This program is used to completely generate the variants of the fast entry, which exist for different applications (for example, post document).
The parameters Program and Application can be recognized in the respective configuration menu (example: Bus.transactions -> Base parameters -> Display format and then Object -> Fast entry) in the upper part of the screen where the variants are listed.
In the configuration menu, a regeneration is only carried out when the variant is changed; this restriction does not apply to this program, the variants are generated without having been changed.

Payment Methods How it works
Payment Method (PM)
Vendor Master (VM)
+PM in the VM - are the allowable PMs if the invoice PM is left blank.
+PM in the Invoice - overrides what is in the VM.
+PM in the payment program(F110) looks for invoices with a matching PM.
For example:
Vendor 1 PM = C
Invoice a PM = blank
Invoice b PM = M
Invoice c PM = C
Invoice d PM = D
F110 PM = CM will create a payment for:
Invoice a PM => C (PM came from the VM, if the VM PM was blank, this invoice would not have been created)
Invoice b PM => M (invoice overrode VM PM)
Invoice c PM => C (invoice overrode VM PM)
Invoice d PM => not selected by F110

Create the event in SM62 (i.e. DTEST_EVENT)
Create a job to run after event SM36(i.e. DTEST_JOB)
Create a program on SAP server (i.e. d:\Raise_DTEST.cmd)
Run the program.
The magic command in the program is:
sapevt -t name= nr=
(i.e. sapevt DTEST_EVENT -t name=DEV nr=00 )
EVENTID is the name of the SAP defined event to raise
-t will create a trace file
the program must have access to \\\sapmnt\\SYS\exe\run

Configure FB10 - Invoice Fast Entry
Q: How can I add House Bank to FB10 (Invoice/Credit Memo Fast Entryscreen)?I was able to activate the field for FB60 by using "Maintain FieldStatus Variants" in the IMG, but this does not seem to change the FB10screen. O7E5 doesn't seem to have house bank as a possible entry.Thanks for your assistance.
A: Which screen are you referring to? Please confirm is it for programSAPMF05A and screen 127. These details you can get it from menu patchSystem --> Status. You can enable or disable list of possible fieldsif they are available in the corresponding screen layout editor viaSE51. I checked in our test system for tcode FB10 and noticed that inthe screen 127 there is no possibility of having 'House Bank' fieldsince the availability of field on this screen doesn't exist. Hope thisinformation clarifies your query. Should the problem is resolved pleaseclose the message. Please do not hesitate to revert me in case you haveany queries with necessary info like, program name and screen number tocheck the possibility of having 'House Bank' field.
R: I was able to active house bank for transaction FB10, however, it was not on the initial screen and was difficult to get to. Based on this and SAP's response, I've decided to modify SAPMF05A screen 8001 (FB10, entry template Z003) to include house bank. A modified version of this screen is already in production and it has a repair open in DEV that I'll have to clean up and/or close as not to migrate it to PRD. Otherwise, this looks like it will be a good solution for the users to choose/override the bank determination logic.

OK_CODE to '=/BDA' when you want to give a user control at a specific screen during a call transaction
Set OK_CODE to '=/BDA' when you want to give a user control at a specific screen during a call transaction.
So instead of run mode A where you see all the screens or run mode E where you only see the errors, you can use run mode N and then stop the program on a specific screen and give the control to the user. When the user finishes the transaction the control goes back to the program, I think.
