Dynamic ALV issue regarding filling of fieldcat

Hello SAP Community,

  • My requirement is to build a Dynamic ALV in which earning, Deduction, Net value fields are to be filled dynamically through by calling FM Evaluation Class. Now the issue is internal table is filled accordingly but when I am calling call method create dynamic table, fieldcat is not filled accordingly in short I am not able to fill the dynamic Column. Hereby I am attaching the code for your reference.

And I am getting garbage values at various places. Can anybody guide me.

Hi Jinson,

please try to generate dynamic structures and tables with the classes

CL_ABAP_STRUCTDESCR, CL_ABAP_TABLEDESCR

For the ALV output, you can use the class CL_SALV_TABLE.

Thorsten
