To update the ZTables. You need to do four things
1.Define the internal table of type your Z table.
DATA: itab type standard table of Z table
2.1. Upload your text file into the internal table using
FM GUI_UPload
here the filetype is 'ASC' as it is a text file
3. Validate your data in the internal table with the validations in the Z table. This could be like primary key validations or some fields must be having some check table attached or even date validations.
Otherwise invalid data is going inside your table
loop at itab
Validations for all the fields
endloop.
4. After the validations Lock your table and then modify the table
call function ENQUEUE*TAble
MODIFY Z TABLE from itab
call function DEQUEUE TABLE
Hope this helps
