Back  RFI # 36: MAXIMUM LENGTH OF BINARY DATA ELEMENT

Formal vs. Informal Help Informal Formal

Submitter

Todd Cochrane

Description

The maximum length in the current Data Element Dictionary of the Binary data element is 1E + 16. At one time it was (1015) 1. X12.6 indicates that this element has no defined length. Should the maximum length be deleted? If not, what is the correct value?

Response

It is correct that X12.6 does not restrict the maximum length of a binary data element nor does it restrict the maximum length of a numeric data element. When a data element is defined in X12.3 Data Element Dictionary a maximum length must be specified. The actual length of a Data Element 785 instance is specified in DE 784. Data Element 784 currently specifies a maximum length of 15 which effectively limits the maximum DE length of 785 in the two segments BIN and BDS in which it is used.

Recommendation

The official response to a formal RFI is a letter from the current ASC X12 chair. This website often displays a summary of the RFI. Click here to view a PDF of the letter for this RFI.

Further Discussion: If a Work Request to increase the length of Data Element 784 were to be submitted and approved this would change the maximum length of a DE 785 instance.
