Sync - Decision Functions Checks and Considerations Table

When a Decision function returns False it always skips a sync. Therefore, when writing Decision function code, always refer to the Decision Function Checks and Considerations Table below.

Decision Functions - Code Examples

Example 1

Add a Decision function on the LU schema level to check the source environment and enable the sync of the LUI in the following scenarios:

• First sync of the LUI.
• LU schema has been changed.
• The source environment is Production.

// Init the Boolean by true\
Boolean syncInd = true;\
// Check the source environment\
String env = getActiveEnvironmentName();

// If the active environment is not production, this sync is not the first sync of the instance, and the schema is not changed => do not sync the instance\
if(!env.toLowerCase().equals("prod") && !isFirstSync() && !isStructureChanged())\
    syncInd = false;

// DEBUG- note- the output of getTableName() was added to the log, since when setting 
// a decision function on the LU schema- it runs on each population of every LU table of the
// schema

log.info("fnCheckSourceEnv- table name: " + getTableName() + ", active env: " + env.toLowerCase() + ", isFirstSync: " + isFirstSync() +
", isStructureChanged: " +  isStructureChanged() + ", Sync indicator: " + syncInd.toString());\
return syncInd;

Example 2

Add a Decision function on the population level in an LU table which is populated only when run on a Development source environment. When run on a Production environment, do not populate this table, since this table does not exist in the Production DB.

// Init the Boolean by true\
Boolean syncInd = true;

// Check the product version (application version) global. Populate ACTIVITY table only of the source version is 'dev'\
String prodVer = SOURCE_PRODUCT_VERSION;

if(!prodVer.toLowerCase().equals("dev") )\
    syncInd = false;

// DEBUG
log.info("fnCheckSourceVersion- product version: " + prodVer + ", isFirstSync: " + isFirstSync() + ", isStructureChanged: " +  isStructureChanged() + ", Syc indicator: " + syncInd.toString());

return syncInd;

Example 3

Add a Decision function on the CASE LU table to check if the CONTRACT LU table has been updated. The check is based on a session level Global (key) which is set to True by the population of the CONTRACT LU table.

// Init the Boolean by true\
Boolean syncInd = true;\
// Check the UPDATE_CONTRACT session level key.\
syncInd = UPDATE_CONTRACT ;\
return syncInd;

Example 4

Add a Decision function on the LU schema level to check if the current time is during peak hours or if this sync is the first sync of the LUI. If the current time is during peak hours and the instance already exists in Fabric, skip the sync of the LUI.

Boolean syncInd = false;\
Boolean offPeak=true;\
LocalTime start = LocalTime.parse( "09:00:00" );\
LocalTime end = LocalTime.parse( "17:00:00" );\
LocalTime now = LocalTime.now();

if(now.isAfter(start) && now.isBefore(end))\
    offPeak=false;

if(isFirstSync() || offPeak)\
    syncInd = true;

// DEBUG\
log.info("now: " + now.toString()+ ", is offPeak: " + offPeak + ", now: " + now.toString() + " , isFirstSync(): " + isFirstSync() + " sync ind: " + syncInd);

if(!syncInd)\
     skipSync();

return syncInd;

Note that the fnCheckSourceEnv, fnCheckSourceVersion, and fnCheckOffPeak functions are displayed in the Demo Fabric Project under the Java tab under the CRM LU folder.
