Figure 3.12.21-1 displays a part of the error register. In this case, the figure provides an example regarding the use of Action Code 3, which rejects the record. This document is unprocessable. An edited 3 is entered to the left of Section 01. An arrow is pointing to the Document Locator Number 00251-165-12900-3. A second arrow is pointing to Field C (MFT Code) 01, which has an asterisk to the left of it, identifying it is in error. The third digit (Tax Class) in the Document Locator Number, 2 (i.e., Individual Income Tax, Fiduciary Income Tax, or Partnership Income Tax), is the error, since Field 01-C on the error register contains an 01 (i.e., Withholding and Social Security - Form 941). The record must be rejected from the register and reinput. The Action Code 3 is used to reject the record as unprocessable.
