I got one here where the compiler thinks the external data structure has no subfields.
In context:
NOTE:
KMT is an externally described data structure based on the same file that the MT data structure ia based on.
CS15L00105 is a logical file based on that same PF, and its only record format is CS15R05K. I want

KMT = MT ;
CHAIN (<Key-field list>) CS15L00105
UPDATE CS15R05K KMT


The Update statement gets this diagnostic error:

Message . . . . : The data structure KMT is not allowed for the operation.
Cause . . . . . : For operation codes CHAIN, READ, READC, READE, READP,
READPE, and UPDATE, the data structure does not consist of the input
fields
of the specified file or record format. For operation code WRITE, the
data
structure does not consist of the output fields of the specified record
format. For operation code EXFMT, the data structure does not consist
of all
the fields fields of the specified record format. The data structure is
ignored.
Recovery . . . : For an input or update operation, define the data
structure using *INPUT or *ALL for the usage parameter of LIKEREC or
EXTNAME. For an WRITE operation, use *OUTPUT or *ALL for the usage
parameter. For an EXFMT operation, use *ALL for the usage parameter.
Compile again.
