Enhace code for 0MATL_GROUP_TEXT datasource using exit_saplrsap_003

Hi,

I did enhance the 0MATL_GROUP_TEXT data source for that

appending the material group long description field to extract structure ROTEXTSTR1 and then uncheck the hide and field only options in data source.

I need ABAP code to populate the field values from table T023T into data source using exit_saplrsap_003.

if any body knows the code, pls come across.

Thanks in advance
