Hi,
I have a lot of procedures that call another procedures to generate a
report.
Then after alter the output parameters of a procedure i can't drop another
procedure that use the one wich had the parameters changed. This is the
error message i got.

This operation is not defined for system tables.
unsuccessful metadata update.
ERASE RDB$PROCEDURE_PARAMETERS failed.
invalid request BLR at offset 1853.
column GRUPO is not defined in table GET_CUSTO_PROD_ORCAMENTO.


How can i solve this?

Until now i'm reediting the procedure to the original parameters, then
dropping the dependent procedure.

TIA.
