Symptoms
During navigation between CCPv2 screens a loading animation is shown. However, during first-time load of any Marketplace Service Plans category, a significant delay may occur (depending on plans quantity) and there will be no loading animation. Loading time increases exponentially with amount of configured Plans on BA side. During this delay no loading animation is shown.
The source of delay is the following request:
https://cp.provider.tld/aps/2/resources/{UID}/pc/sales-category/70046/plans?sort(+showPriority)
It uses BA APS integration to invoke method BM.PlansListFeesWithTaxesGet_API on BA side which fetches all required data from requested service plans. The method takes 5-6 seconds to complete and consists of 1260+ DB queries for 25 plans.
Cause
Slowness of BM.PlansListFeesWithTaxesGet_API is recognized as a software-related issue PBA-80667: "Performance problem in PlansListFeesWithTaxesGet_API".
The absence of any loading animation is considered as another point of improvement - PBA-80087.
Resolution
Both concerns do not have workaround at the moment. Please contact your Technical Manager or PTA team to know more about statuses of aforementioned issues.
