How 2 add text (BSEG-SGTXT) for a particular G/L of a Document (FB02) ?

Question

Hi,
The standard program RFBIBL00 does FAE(FI) posting in our custom program.
For doing so, we are passing a file with all the revenue G/L account details based on the structure BSEG.
The standard program creates a document for the FI posting.
When we view the document in transaction FB03, posting has been made for all the revenue G/L accounts and
also the corresponding VAT G/L accounts and the exact Tax amount has been determined by the standard program and posting has been made for the same.
But the Text field (BSEG-SGTXT) is empty for the VAT G/L accounts, since those account details has been determined in run-time by the standard program.
NOTE: Text fields have the constant value only for the revenue G/L accounts, since we pass to the file to the standard program only for the revenue G/L accounts.
Our requirement is to add the value in the text field for a particular VAT G/L account.
Kindly suggest few methods to add the constant value in the text field for a particular G/L account of the document through our custom program.
Thanks in Advance.
Yogesh.

Answer 1

Thanks for your quick answer,
I have checked the table BSAS as well, it also has no entries corresponding the above G/Laccount.
I can find the entries in BSEG for that G/L, but since it does not have the G/L account as primary key
my program will take very long processing time as the user will give range of G/L accounts.
When I Check the Report FS10N with the same G/L account, and double click to see the lineitems
it also gives me the message 'no line items found' eventhough it shows some amount in the first screen.
