Add field in standard ALV report.

Hi friends,

In SAP standard ALV report, t.code- S_ALR_87012050, user wants the vendor to include information about source document - vendor number, vendor name, invoice number, original document number of the transaction in the case of payroll being capitalized.

I tell me weather this information is already present in the report or I have to create Z report for adding this information and how do I proceed to add new fields in the created Z program.

Please help me.

Thanks in advance,

Saya
