BKPF-XBLNR (Reference Field is not changeable)

[sachin_thombre]

Hello All,

We have a existing config, to allows change of field BKPF-XBLNR.

When I enter the document manually F-02, I am able to change the BKPF-XBLNR after the document is posted

We have a case, where accounting doc is posted via Purchase Order and due to some reason we want to change the BKPF-XBLNR field, and system is not allowing to change. Is this happening because the accounting doc is posted via Purchase Order? If we want to change these kinds of document is there any other way?

Hi,

Is your system S/4 HANA?
Have you confirmed that there are entries for BSEG in SE16N?

If does not exist, please check table ACDOCA, this is a table integrating financial module data.

If the data is in the table, it cannot be changed

Or check T-code：OB32?

Does field XBLNR assign a specific transaction type?
