It doesn't matter if the format names match in the PF and LFs.
I created the following DDS members
JRSTESTPF
R RTESTPF
FIELD1 10
FIELD2 10
FIELD3 10
K FIELD1
K FIELD2
JRSTESTLF1
R RTESTPF PFILE(JRSTESTPF)
K FIELD2
K FIELD1
JRSTESTLF2
R RTESTPF PFILE(JRSTESTPF)
FIELD1 10
FIELD2 10
FIELD3 10
K FIELD3
K FIELD2
Note that JRSTESTLF2 has the fields included in the DDS.
The record format IDs on all three files match.
I changed FIELD1 from 10 to 20
JRSTESTPF R RTESTPF
FIELD1 20
FIELD2 10
FIELD3 10
K FIELD1
K FIELD2
And then do a CHGPF on JRSTESTPF
FIELD1 in JRSTESTPF is changed to 20
FIELD1 in JRSTESTLF1 is changed to 20
FIELD1 in JRSTESTLF2 is NOT changed. It remains 10 bytes.
Also, the record format ID on JRSTESTPF and JRSTESTLF1 match. JRSTESTLF2 no longer matches.
