Relationships to earlier versions of the elements

If the element entry in your target zone has an RMID value different from its FMID value, ensure it is a prerequisite of the USERMOD fix; that is, make sure the bbbbbbb value shown in the example is accurate. If the RMID and FMID values are equal, the bbbbbbb value need not be specified.
If the element entry in your target zone has any UMID values, you should first check to make sure the USERMOD itself was constructed so it works correctly in that environment. You should then make sure each of the UMID values is specified in the PRE operand in place of the ccccccc values shown in the example. This is not an absolute requirement, but if it is omitted, SMP/E issues warning messages during installation identifying that these SYSMODs may have an intersection with the one you are installing and, therefore, may be regressed. Putting the UMID values in the PRE list suppresses these messages.
If you do not specify the requisites that previously replaced an element, SMP/E does not allow your USERMODs to be installed unless you specify BYPASS(ID) on the APPLY or ACCEPT commands.
If you want this SYSMOD installed without any warning or error messages, you must specify all the current UMID values of each element in the SYSMOD in the PRE operand. This indicates to SMP/E that the SYSMOD was designed to be installed on the current function and service level of the element, including update level.
If you do not specify the requisites that previously updated an element, the following occurs:
- If your SYSMOD contains an element replacement, SMP/E does not allow the SYSMOD to be installed unless BYPASS(ID) is specified on the APPLY and ACCEPT command.
- If your SYSMOD contained an element update, SMP/E allows the SYSMOD to be installed, but issues a warning message for each requisite not specified in the PRE list.
This means SMP/E is unable to determine if there is an intersection between your update and those already on the element. It assumes that there is none, and you should investigate both updates to verify this.
