How do I debug the INSERT, UPDATE table syntax?I'm getting sy-subrc = 4.

[walkerist79]

I was trying to use Insert, Update on updating a table.

I was trying to insert and update 4 different fields.

When Inserting into table named Z_LOCAL, only 3 fields were inserted even though 4 fields were expected  to be inserted.

INSERT Z_LOCAL FROM TABLE LT_ZLOCAL_INSERT.

And when updating, i'm getting sy-subrc = 4.

UPDATE Z_LOCAL FROM TABLE LT_ZLOCAL_UPDATE.

You cannot debug this. The ABAP documentation explains well why you get SY-SUBRC = 4. Make sure your table is correctly activated with all the columns you have defined. Make sure that the declaration is: DATA lt_zlocal_insert TYPE TABLE OF z_local, and the same for lt_zlocal_update.

@Sandra_Rossihere is how ideclared the LT_ZLOCAL_UPDATE and LT_ZLOCAL_INSERT

LT_ZLOCAL_UPDATE TYPE STANDARD TABLE OF Z_LOCAL,
LT_ZLOCAL_INSERT TYPE STANDARD TABLE OF Z_LOCAL.

This doesn't make sense: "3 fields were inserted"? You may have 3 lines/rows inserted, not fields.
