ABAP - BDC transaction not saving changes to records

[Former Member]

I am trying to write my first ABAP code using BDC recording. Essentially I would like to flag the "Final Delivery" field (EKPO-EGLKZ) for a range of documents by recording transaction MASS.

The code runs without errors - but the changes are not saved. I have run the code in "Processing Mode: A" (Display all screens) and the program successfully loops through each record & saves the updated fields. When I look at the documents in ME23N the changes have not been saved. Running the MASS transaction manually results in the changes being successfully saved so I can rule out any data validation issues.

Does anyone know why the changes refuse to save when running the code below?

I have considered trying to use BAPI_PO_CHANGE instead of BDC, but I am new to ABAP and I thought the BDC code would be less complex.

Where is BDC_INSERT.

If u use OPEN and CLOSE_group u need to use INSERT_GROUP also to update in database.

A session will be created and u nedd to run the Session in Sm35 in order to update the database.

Hi,

try this

Write your loop statements after

perform open_group
