utilities- need replacement for FM ISU_DER_RESET_CROSS_REF_NO

Hi experts,

The Function module ISU_DER_RESET_CROSS_REF_NO does not exist in ECC.

This FM used in 4.7 version and as part of upgradation , I need to retrofit(fix) this.

I have searched for this FM in the forum, but could not find. Documentation for this FM even in 4.7 version could not be found.

Please help me to find the replacement for this FM in ECC.
