Getting error when calling Stored Procedure in script

Hi,

I am getting an error on while executing stored procedure on oracle 11g db as source by calling below in the script BODS 4.1.

sql( 'ds_xxx','begin schemaxxx.PAC_xxx_LOAD.PRC_xxx;end;');

sql( 'ds_xxx','begin schemaxxx.PAC_xxx_LOAD.PRC_xxx;end;');

sql( 'ds_xxx','begin schemaxxx.PAC_xxx_LOAD.PRC_xxx;end;');

Steps:

1. Imported SP into functions

2. Called stored procedure in script

Error:

1st SP is executing correctly and when it executes 2nd and 3rd SP, am getting below error.

I would appreciate your help on this.
