Question
I have a string field, but sometimes the data contains proceeding zeros and sometimes it does not. I am trying to build a match rule to just match the field based on numeric values without changing the type from string. Can someone help me with this? e.g. 000723 should match 723. When I use the RangeNumericComparator it gives a validation error and says the field type is not correct and will not let me save the L3 / new rule.
{
"exact": [
"configuration/entityTypes/MedicinalProduct/attributes/NDC"
],
"comparatorClasses": {
"mapping": [
{
"attribute": "configuration/entityTypes/MedicinalProduct/attributes/NDC",
"class": "com.reltio.match.comparator.RangeNumericComparator"
}
]
},
"matchTokenClasses": {
"mapping": [
{
"attribute": "configuration/entityTypes/MedicinalProduct/attributes/NDC",
"class": "com.reltio.match.token.RangeNumericMatchToken"
}
]
}
}
Is there pattern to ignore leading zero?
Answer
Please review the following for a solution to the problem.
"parameters": [
{
"parameter": "groups",
"values": [
{
"pattern": "[^0]*[1-9][0-9]*",
"className": "com.reltio.match.token.ExactMatchToken"
}
]
}
],
"class": "com.reltio.match.token.CustomMatchToken"
Example of Match Rule:
{
"exact": [
"configuration/entityTypes/MedicinalProduct/attributes/NDC"
],
"matchTokenClasses": {
"mapping": [
{
"attribute": "configuration/entityTypes/MedicinalProduct/attributes/NDC",
"parameters": [
{
"parameter": "groups",
"values": [
{
"pattern": "[^0]*[1-9][0-9]*",
"className": "com.reltio.match.token.ExactMatchToken"
}
]
}
],
"class": "com.reltio.match.token.CustomMatchToken"
}
]
},
"comparatorClasses": {
"mapping": [
{
"attribute": "configuration/entityTypes/MedicinalProduct/attributes/NDC",
"parameters": [
{
"parameter": "groups",
"values": [
{
"pattern": "[^0]*[1-9][0-9]*",
"className": "com.reltio.match.token.BasicStringComparator"
}
]
}
],
"class": "com.reltio.match.comparator.CustomComparator"
}
