Managing Sync Performance

Attention: SAP Field Service Management documentation is now available at the SAP Help Portal. On 31 December 2020, docs.coresystems will no longer be available. Until that time, documentation will NOT be updated in docs.coresystems.

1 Introduction

The size of your company database has a direct impact on the amount of time required to synchronize data to the mobile application and on the application performance itself.

The following document outlines the scope of impact by database volume and device, how database volume can be viewed, and actions that can be taken to improve data usage, sync performance, and application performance.

1.1 Device Database Size Recommendations

The following table represents the recommended and maximum database size and business object counts for optimal synchronization time performance:

  Database Size Number of Objects
Recommended 400 MB 10,000 objects of any given object (see list below)
Maximum 600 MB 20,000 objects of any given object (see list below)

1.1.1 High Impact Business Objects

The data objects that have the greatest impact on synchronization performance are:

  • Activity
  • Attachment
  • Batch
  • BatchQuantity
  • BusinessPartner
  • Equipment
  • Person
  • ReservedMaterial
  • SalesOpportunity
  • SalesOrder
  • SalesQuotation
  • ServiceCall

1.2 Differences in Devices

The following chart shows data synchronization time in minutes:seconds (mm:ss) at different volume loads of Activities.

1.2.1 Time to Synchronize by Device (iOS / Android)

  5k Activities 10k Activities 20k Activities 50k Activities 100k Activities
Older Android Device 1:02 2:44 5:23 16:59 43:58
Newer Android Device 0:53 2:22 4:30 12:05 29:42
Older iPad 1:07 5:05 12:10 32:17 65:10
Newer iPad 0:23 0:48 01:21 04:43 11:21
Older iPhone 1:28 7:48 16:00 41:04 89:05
Newer iPhone 0:19 1:19 1:34 5:26 13:46 Device Details
Note: iOS is faster than the equivalent Android device when performing a sync, as iOS uses a proprietary binary format which is more efficient.
Type Device OS
Older iPhone iPhone 4S (MC918LL/A) iOS 9.3.2
Older iPad iPad 3 64GB (MC707FD/A) iOS 9.3.2
Newer iPhone iPhone 6S (MKQT2ZD/A) iOS 10.2
Newer iPad iPad Pro (MLMN2TY/A) iOS10.1.1
Older Android Sony Xperia Z5 Compact 6.0.1
Newer Android Google Pixel 7.1.1

1.2.2 Time to Synchronize by Device (Windows)

The following chart shows data synchronization time in minutes:seconds (mm:ss) at different volume loads of Activities.

  5k Activities 10k Activities 20k Activities 50k Activities 100k Activities
Newer Desktop 0:05 0:10 0:20 0:40 1:20
Newer Laptop 0:07 0:15 0:20 0:50 1:40
Older Laptop 0:05 0:15 0:25 1:05 2:35 Device Details
Type Device OS
Newer Desktop Desktop 2015 i5-4690k SSD Windows 10 64-bit
Newer Laptop Laptop 2012 i5-2520m NO SSD Windows 10 64-bit
Older Laptop Laptop 2011 i7-2620m SSD Windows 10 64-bit

1.3 Background Apps and Performance

Background apps and processes running on a device will impact full-sync performance. This generally includes apps such as maps, navigation systems, music players, etc.

2 Establishing a Baseline

In order to determine the efficacy of remediate action, you will need to establish a baseline.

2.1 Viewing Object Count from Mobile

Business object counts can be viewed from the mobile app by completing the following steps:

  1. Navigate to Settings and select Contact Support from the action menu (⋮).
  2. The application will display the business object counts for high impact business objects and other business objects in the body of an email:

  3. If you don’t wish to send an email to SAP FSM Support, select the Cancel option from the top.
Note: Business object counts viewed from the mobile applicaiton take into account both user permission settings and relevant company settings.

2.2 Viewing Company Object Count

Company business object counts can be viewed using the Query API tool located in the Admin Module.

The following query can serve as a template for returning a maximum count for business objects that could be sent to the mobile application:


Here, Activity can be replaced by another business object to return a count (example: BusinessPartner).

Note: To return a count for a specific account (such as a technician), you could use an API management tool such as Postman and pass the account credentials into the request sent to the Query API.

3 Taking Action

The following actions can be taken to improve performance and synchronization times.

Permissions can be applied to users and business objects to further customize behavior and improve performance. For example, a user could be assigned Read permissions for their Own Activities, filtering out activites that are assigned to other employees.
Data Sync Rules
Data Sync Rules can be applied to determine what data is stored in the mobile app when in "offline" mode.
Company Settings
Company settings can be adjusted to reduce attachment display size a
