Xblnr_alt update via function module or IRBM no field for malaysia

[adityajan]

Hello Members,

Would you please let us know the functional module to update the XBLNR_ALT field to update the IRBM number for Malaysia.

We are not using  the solution provided by SAP for Malaysia e-invoicing.
We are trying to use XBLNR_ALT field to update the IRBM number via FM. If there is any other field we can use to store the IRBM number in the FI document number, please let us know.

thanks in advance

Why didn't you use standard SAP solution?

Actually SAP will try to prevent you to update this fiedl (it's expected this field will automatically contain the ODN, original document number, in some case, countries)

• Read 3399198 - BKPF-XBLNR_ALT not editable in FB02 

You could try to use other fields

• Look for available XREF* fields such as XREF1_HD, XREF2_HD, or even BKTXT,
• Some long text at header level
• Any appended ZZ-fields, but in last case some substitution and/or BAdI/BTE implementations would be required
