This section contains the common SMF record headers fields and the triplet fields (offset/length/number) that locate the other sections on the record.
| Offsets | Name | Length | Format | Description | |
|---|---|---|---|---|---|
| 0 | 0 | SMF90LEN | 2 | binary | Record length. This field and the next field (total of four bytes) form the RDW (record descriptor word). See Standard SMF record header for details. |
| 2 | 2 | SMF90SEG | 2 | binary | Segment descriptor (see record length field). |
| 4 | 4 | SMF90FLG | 1 | binary | System indicator:

| 6 | 6 | SMF90TME | 4 | binary | Time since midnight, in hundredths of a second, that the record was moved into the SMF buffer. |
| 10 | A | SMF90DTE | 4 | packed | Date when the record was moved into the SMF buffer, in the form 0cyydddF. See Standard SMF record header for a detailed description. |
| 14 | E | SMF90SID | 4 | EBCDIC | System identification (from the SID parameter). |
| 18 | 12 | 2 | Reserved. | ||
| 20 | 14 | SMF90POF | 4 | binary | Offset to product section from start of record, including the record descriptor word (RDW). |
| 24 | 18 | SMF90PLN | 2 | binary | Length of the product section. |
| 26 | 1A | SMF90PON | 2 | binary | Number of product sections. |
| 28 | 1C | SMF90DOF | 4 | binary | Offset to subtype data section from start of record, including the record descriptor word (RDW). |
| 32 | 20 | SMF90DLN | 2 | binary | Length of subtype data section. |
