ITEM_COUNT field of CSAP_MAT_BOM_MAINTAIN getting wrongly passed through JCo.

Even after passing the value of ITEM_COUNT of function module CSAP_MAT_BOM_MAINTAIN as 00000000 (which is its default value), the SAP is getting the value as 00000 00 and then throws an exception for data-type.

Exception detail:

java.sql.SQLException: Exception while executing the remote function Unable to interpret 00000 00 as a number.

{Value passed by me here is 00000000}
