We upgraded from GP 2015 to GP 2018 and have been unable to process ACH's to our vendors in payables due to the following error; "You cannot post. The fiscal period that contains this posting date has not been set up." -- Our fiscal periods are set up and we are able to run and print checks in payables. Payroll ACH batch ran as well--thankfully.
I am able to "force" through the batch, but only the first vendor is assigned a payment document number, the document number for all other vendors in the batch are blank.We are operating on Plan B (all vendors are getting checks).
I noticed a wacky thing with the posting date and batches...not sure if this is your issue...but here is what I saw.
If the Administration > Setup > Posting > Posting for Purchasing > Computer Checks was setup to "Posting Date from Transaction"...the batch defaulted to having a Posting Date of 0/0/00. (Usually that field is greyed out). Can you try putting a date in that field or changing your setup to Posting Date from Batch. Here is the wacky date.
