Answer / manish

The field catalog is a table which contains information on the fields to be displayed on the ALV output.
First we need to build a field catalog before displaying any output in the ALV. We have the following three ways to build a field catalog.
To generate a field catalog semi-automatically:
Declare an internal table of type SLIS_T_FIELDCAT_ALV.
Call function module REUSE_ALV_FIELDCATALOG_MERGE and pass the DDIC structure of the output table and the internal table for the field catalog. The function module generates the field catalog and fills the internal table accordingly.
Read the rows you want to change, and adapt the fields accordingly. If your output table contains more fields than are stored in the Data Dictionary, you must append one row for each new field to the field catalog.
