Program RBDMANI2 giving error RV45A-VBAP_SELKZ(2) is not an input field

Hi All,

We have an issue where our IDOC gets posted in the production system with status 51. We schedule a job twice a day in the background using program RBDMANI2 which is used to manually reprocess IDOCS in error. Every time the IDOCS with this error are still getting failed with the same error.

But, when the same error idocs are executed using BD87 in foreground or background, the idocs are successfully and the sales orders are created.

Please help me why this issue is happening and if there is any sap note for this error.

Thanks,

BK
