Replace the ChkImp_C fileset in main data from initdata
Assuming the site has done no business for the day (this problem manifests at the start of the day) delete all daily files from main data. You can do this easily by searching for ??DDMMYY.* in main data (november 20th 2019 would be ??112019.*).
Edit VMDTRN_C and remove all entries where the second column contains a 9 (Paymentech)
