Rule blocked: CORERULES-558

**Links to related JIRA Tickets**
- https://jira.cdisc.org/browse/CORERULES-558

**Rule Information**
- **SENDIG**:
- **106**:
- **Rule Description**: If strain information is not included in DM it must be included in TS.
i.e. when the "STRAIN" variable is absent in DM, there must be a record in TS with TSPARMCD=STRAIN

**Describe the bug**
Gerry made a first prototype of an implementation in YAML. When tested on a positive (but also negative) Excel test file, it produces an error for DM.

**Error returned from Rule Engine**
{
"TS": [
{
"executionStatus": "skipped",
"domain": "TS",
"variables": [],
"message": null,
"errors": []
}
],
"DM": [
{
"executionStatus": "execution_error",
"domain": "DM",
"variables": [],
"message": "rule execution error",
"errors": [
{
"error": "An unknown exception has occurred",
"message": "index 0 is out of bounds for axis 0 with size 0"
}
]
}
]
}

**Expected behavior**
Gerry thinks another approach, maybe with new functions, should be taken
