srilata83, you don't say but it looks like you are using DB2 z/OS based on the Load syntax.
NOCHECKPEND is not an option you can use with the Load utility.
You problem may be solved by running your load statements in an order that will eliminate the Check Pending status. For example if you have 3 tables in an RI string like:
Table1 parent to Table2 parent to Table3
and you ran the Load on Table3 and then Table2, Table3 will be left in Check Pending because its parent table was Loaded. However, if you ran the Load on Table2 and then Table3, no tables would be left in Check Pending.
