_ant_generate_db fails with ERROR : Could not replace text.... when a procedure in cust layer overtakes the ext layer

Hi,

• PROCEDURE Create_Connectivity_Message___ of InvoiceTransfer-Cust.plsql overtakes the Ext layer(PROCEDURE Create_Connectivity_Message___ of InvoiceTransfer-Ext.plsql)
• There are 5 $SEARCH and $REPLACE blocks within the procedure in the cust layer and one $SEARCH and $APPEND block.
• Encountered the error
  • "Exception while generating code for InvoiceTransfer-Cust.utility Could not replace text " IF (send_itxml_ AND doc_type_ = 'TD04') THEN ..." in method Create_Connectivity_Message___"

        for the 3rd $SEARCH and $REPLACE block "IF (send_itxml_ AND doc_type_ = 'TD04') THEN"      which  has been written after the $SEARCH and $APPEND block.

• I would like to know how to correct this type of an error when we want to implement several $SEARCH and $REPLACE blocks along with $SEARCH and $APPEND within the same procedure in the cust layer that overtakes the ext layer.

Cheers,

Priyanjala
