Customers that are both active and interested should receive a phone call:
code| trans |
|---|
| RawWrangle | true |
|---|
| p03Value | 'phoneCall' |
|---|
| Type | step |
|---|
| WrangleText | derive type:single value:AND(isActive, isInterested) as:'phoneCall' |
|---|
| p01Name | Formula type |

| p01Value | Single row formula |

| p02Name | Formula |
|---|
| p02Value | AND(isActive, isInterested) |
|---|
| p03Name | New column name |
|---|
| SearchTerm | New formula |

|
Customers that are either active or interested should receive an email:
code| trans |
|---|
| RawWrangle | true |
|---|
| p03Value | 'sendEmail' |
|---|
| Type | step |
|---|
| WrangleText | derive type:single value:OR(isActive, isInterested) as:'sendEmail' |
|---|
| p01Name | Formula type |

| p01Value | Single row formula |
|---|
| p02Name | Formula |
|---|
| p02Value | OR(isActive, isInterested) |
|---|
| p03Name | New column name |
|---|
| SearchTerm | New formula |
|---|
|
Customers that are neither active or interested should be dropped from consideration for the offering:
code| trans |
|---|
| RawWrangle | true |
|---|
| p03Value | 'dropCust' |
|---|
| Type | step |
|---|
| WrangleText | derive type:single value:AND(NOT(isActive),NOT(isInterested) as:'dropCust' |
|---|
| p01Name | Formula type |
|---|
| p01Value | Single row formula |
|---|
| p02Name | Formula |
|---|
| p02Value | AND(NOT(isActive),NOT(isInterested) |
|---|
| p03Name | New column name |
|---|
| SearchTerm | New formula |
|---|
|
A savvy marketer might decide that if a customer receives a phone call, that customer should not be bothered with an email, as well:
code| trans |
|---|
| RawWrangle | true |
|---|
| Type | step |
|---|
| WrangleText | set col:sendEmail value:IF(phoneCall == "TRUE", FALSE, sendEmail) |
|---|
| p01Name | Columns |
|---|
| p01Value | sendEmail |
|---|
| p02Name | Formula |
|---|
| p02Value | IF(phoneCall == "TRUE", FALSE, sendEmail) |
|---|
| SearchTerm | Edit column with formula |
|---|
|
Results:
| Customer | isActive | isInterested | dropCust | sendEmail | phoneCall |
|---|
| CustA | Y | Y | FALSE | FALSE | TRUE |
| CustB | Y | N | FALSE | TRUE | FALSE |
| CustC | N | Y | FALSE | TRUE | FALSE |
| CustD | N | N | TRUE | FALSE | FALSE |
