A view-only array of 4 characters, each with a specific meaning and purpose. Sites use it to optionally group blocks, to define blocks as transfer areas, to control dispatch behavior to trucks, or to define the straddle exchange grid or area association. See Understand Code Chars (on page 1) for more information.

You configure this field in the General tab of the Stack Block form (on page 1) and for non-stack blocks, in the Non-Stack Block form.

For sites using transfer zones (such as ASC operations), to ensure XPS completes work instructions properly, you must configure this field accordingly. For more information, see Affiliation Code for blocks with transfer zones (on page 1).

If your site uses codeChars[4] to define exchange area to block associations, you must set MULTYD (on page 1) to N. The default value for this setting is Y. When MULTYD is set to Y, the XPS server and XPS clients fail to deck if the allocation is in a different CodeChar[4] block than the current position of the container.

The type of the block. This corresponds to the block type code in XPS.

See Block types (on page 1) for a list of available block types.

See the Table of block type codes (on page 1) for a full list of block types, the corresponding code in XPS, and the configuration style.

Logical block purpose, such as APRN, EQPC, or FDEC.
