The SCLM change code is an 8-character identifier used to indicate the reason for an update or modification to a member controlled by SCLM. This code can be used to track changes made to source members. The change code exits in SCLM to verify that a valid change code has been entered. This also enables the grouping of members for build and promote functions. The change code can be applied to track code changes related to reported defects or enhancements.
