Reg. Updation of PRPS table columns .use of BAPI_BUS2054_CHANGE_MULTI

Hi,

I have used the sequence of BAPI calls as provided below.

BAPI_PS_INITIALIZATION

BAPI_BUS2054_CHANGE_MULTI

BAPI_PS_PRECOMMIT

BAPI_TRANSACTION_COMMIT

I would like to update some columns of PRPS table for specified WBS element, uploading data from an excel sheet.

I get the data from excel sheet to an internal table and pass to BAPI_BUS2054_CHANGE_MULTI row by row.

It's strange ! .it updates every column for all the row of data w.r.t WBS element But location field for first row data element get updated and rest ignored.

can you please suggest me why it happens so?

Thanks in advance.

Regards,

Sourya Prakash.
