How To Fix JIT00302 - Enter as many production lines as possible

SAP Error Message - Details

• Message type: E = Error

• Message class: JIT00 - JIT: Messages for JIT Process

• Message number: 302

• Message text: Enter as many production lines as possible

What causes this issue?

If you do not enter a production line you have to carry out the
progress confirmation for all production lines.

System Response

The test procedure for establishing the completeness of sequenced JIT
call sequence numbers is very lengthy if you have not entered a
production line. It is more efficient to list all production lines
individually. In this case, the system checks the completeness of the
components groups to be reported to a sequence number, against the
lines entered.

How to fix this error?

For this purpose you can enter the same line several times. The system
begins with a complete JIT call header, if the number of components
groups corresponds to a sequence number of the number production lines
entered.
&Example&
On a specific line you produce two components groups per call. Here,
enter the production line twice. The system saves up to 4 production
lines using USER-parameter JITF_LINE_A bis JITF_LINE_D.
